Vulnerability in @beproduct/nestjs-auth (CVE-2026-46412)
Summary
Vulnerability in @beproduct/nestjs-auth (CVE-2026-46412). Successful exploitation can lead to full system takeover. Exploitable via tanstack_runner.js.
Original description
The description as published by the source.
Summary
Between 2026-05-11 20:19 UTC and 22:56 UTC, an attacker used a compromised npm publish token to publish 18 malicious versions of @beproduct/nestjs-auth (0.1.2 through 0.1.19). The packages contained payloads from the Mini Shai-Hulud npm supply-chain worm campaign described by Aikido Security.
npm Security removed the malicious versions from the registry shortly after publication, but anyone who ran npm install @beproduct/nestjs-auth resolving to any version in the affected range during that window executed the malicious postinstall script and is potentially compromised.
Version 0.1.20 is a clean republish from the original 0.1.1 source tree.
Impact
The postinstall payload attempted to harvest:
- npm tokens (from
~/.npmrc) - GitHub personal access tokens, OAuth tokens (
gho_*), and Actions OIDC tokens - AWS credentials (from environment variables and
~/.aws/credentials) - HashiCorp Vault tokens
- Other secrets present in environment variables
Exfiltration target: https://filev2.getsession.org. The worm also wrote persistence artefacts (tanstack_runner.js, router_init.js, setup.mjs, plus IDE-hook configurations in .claude/ and .vscode/) into the developer's working tree where the malicious install ran.
Indicators of compromise
